Consider the following hypothesis test: H 0: 20 H a: < 20 A sample of 50 provided a sample mean of 19.4. The population stand
goblinko [34]

Answer: p-value is 0.016.

Step-by-step explanation:

Since we have given that

H_0:\mu=20\\\\H_a:\mu

Sample mean = 19.4

Sample size n = 50

Standard deviation = 2

We need to find the test statistic value which is given by

z=\dfrac{\bar{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}\\\\\\z=\dfrac{19.4-20}{\dfrac{2}{\sqrt{50}}}\\\\\\z=\dfrac{-0.6}{0.28}\\\\z=-2.14

p-value is given by

P(Z>Z_{critical})\\\\=P(Z>-2.14)\\\\=0.016

Hence, p-value is 0.016.
